  • Creating a shared library that might be used with desktop applications and web projects

    - by dreza
    I have been involved in a number of MVC.NET and c# desktop projects in our company over the last year or so while also managing to kept my nose poked into other projects (in a read-only learning capacity of course). From this I've noticed that across the various projects and teams there is a-lot of functionality that has been well designed against good interfaces and abstractions. Because we tend to like our own work at times, I noticed a couple of projects had the exact same class, method copied into it as it had obviously worked on one and so was easily moved to a new project (probably by the same developer who originally wrote it) I mentioned this fact in one of our programmer meetings we have occasionally and suggested we pull some of this functionality into a core company library that we can build up over time and use across multiple projects. Everyone agreed and I started looking into this possibility. However, I've come across a stumbling block pretty early on. Our team primarily focuses on MVC at the moment and we have projects mainly in 2.0 but are starting to branch to 3.0. We also have a number of desktop applications that might benefit from some shared classes and basic helper methods. Initially when creating this DLL I included some shared classes that could be used across any project type (Web, Client etc) but then I started looking at adding some shared modules that would be useful in our MVC applications only. However this meant I had to include a reference to some Microsoft Web DLL's in order to leverage some of the classes I was creating (at this stage MVC 2.0). Now my issue is that we have a shared DLL that has references to web specific libraries that could also possibly be used in a client application. Not only that, our DLL referenced initially MVC 2.0 and we will eventually move onto MVC 3.0 for all projects. But alot of the classes in this library I expect to still be relevant to MVC 3 etc Our code within this DLL is separated into it's own namespaces such as: CompanyDLL.Primitives CompanyDLL.Web.Mvc CompanyDLL.Helpers etc etc So, my questions are: Is it OK to do a shared library like this, or if we have web specific features in it should we create a separate web DLL only targeted at a specific framework or MVC version? If it's OK, what kind of issues might we face when using the library that references MVC 2 in a MVC 3 project for example. I would be thinking that we might run into some sort of compatibility issue, or even issues where the developers using the library doesn't realize they need MVC 2.0 libraries. They might only want to use some of the generic classes etc The concept seemed like a good idea at the time, but I'm starting to think maybe it's not really a practical solution. But the number of times I've seen copied classes and methods across projects because they are proven tested code is a bit unnerving to be perfectly honest!

  • How to connect to database on remote server

    - by user137263
    Where there is VPN to remote server and then access to the database via local network interface, how can one establish a remote link between one's computer (with a programme such as Visual Studio 2010) and SQL Server (e.g. 2008 R2) ? Any attempts to create a direct link to the SQL Server are blocked. Whilst the SQL Server can be configured to allow external access, this provides its own host of problems. Any help would be much appreciated.

  • How can I get my HID device working in VirtualBox?

    - by Andy E
    I'm running the latest official Ubuntu build of VirtualBox (4.1.12), with Windows 8 running as the guest OS.

  • Do I need "cube subclasses" to represent the blocks in a Minecraft-like world?

    - by stighy
    I would like to try to develop a very simple game like Minecraft for my own education. My main problem at the moment is figuring out how to model classes that represent the world, which will be made of blocks of various types (such as dirt, stone and sand). I am thinking of creating the following class structure: Cube (with proprerties like color, strength, flammable, gravity) with subclasses: Dirt Stone Sand et cetera My question is, do I need the Cube subclasses or a single class Cube sufficient?

However, today I just got a message (it seems legitimate) from Google AdSense saying: Congratulations, your AdSense account has been approved to show AdSense ads on your own website. Within a few hours, you will begin to see live ads. Should I be concerned? They say that they review accounts to check for compliance, could this be some weird way of saying they rechecked my sites and they complied?
